title: Thermal diffusion of ⁶⁷Ga from irradiated Zn targets.
abstract: Gallium-67 is a cyclotron produced radionuclide and ⁶⁷Ga-citrate complex scans are performed in a variety of applications in Nuclear Medicine. The aim of this study was to evaluate a new method for the chemical separation of ⁶⁷Ga from Zn targets. The method has 2 steps, first the thermal diffusion of ⁶⁷Ga with concentrated acetic acid and then purification by cation exchange in ammonium medium. The final ⁶⁷Ga solution was obtained in 0.1 mol L⁻¹ HCl with the desirable high purity.
